Aluminum Electrolytic Capacitor

Mar. 2005

Application Guidelines

1. Circuit Design

Ensure that operational and mounting conditions
follw the specified conditions detailed in the catalog
and specification sheets.

1.1 Operating Temperature and Frequency

Electrolytic capacitor electrical parameters are
normally specified at 20°C temperature and 120Hz
frequency. These pa rameter s vary with changes in
temperature and frequency. Circuit designers
should take these changes into consideration.
(1) Effects of operating temperature on electrical
parameters
a)At higher temperatures, leakage current and
capacitance increase while equivalent series
resistance(ESR) decreases.
b)At lower temperatures, leakage current and
capacitance decrease while equivalent series
resistance(ESR) increases.
(2) Effects of frequency on electrical parameters
a)At higher frequencies, capacitance and
impedance decrease while tan δ increases.
b)At lower frequencies, ripple current generated
heat will rise due to an increase in equivalent
series resistance (ESR).

1.2 Operating Temperature and Life Expectancy

(1) Expected life is affected by operating temperature.

Generally, each 10°C reduction in temperature
will double the expected life. Use capacitors at
the lowest possible temperature below the
maximum guaranteed temperature.
(2) If operating conditions exceed the maximum
guaranteed limit, rapid eIectrical parameter
deterioration will occur, and irreversible damage
will result.
Check for maximum capacitor operating tempera­ tures including ambient temperature, internal
capacitor temperature rise caused by ripple current,
and the effects of radiated heat from power
transistors, IC?s or resistors.
Avoid placing components which could conduct
heat to the capacitor from the back side of the circuit
board.
(3)The formula for calculating expected Iife at lower
operating temperatures is as fllows;

T1-T2

L

2 = L1 x 2 where,

1: Guaranteed life (h) at temperature, T1° C

L

1.3 Common Application Conditions to Avoid

The following misapplication load conditions will
cause rapid deterioration to capacitor electrical
parameters. ln addition, rapid heating and gas
generation within the capacitor can occur causing
the pressure relief vent to operate and resuItant
leakage of electrolyte. Under extreme conditions,
explosion and fire could result. Leakinq electrolyte
is combustible and electrically conductive.

(1) Reverse Voltaqe

DC capacitors have polarity. Verify correct polar ity

before insertion. For circuits with chan ging or
uncertain polarity,use DC bipolar capacitors. DC
bipolar capacitors are not suitable for use in AC
circuits.

(2) Charqe/Discharqe Applications

Standard capacitors are not suitable for use in

repeating charge/discharge applications. For
charqe/discharqe applications consult us and advise
actual conditions.

(3) Overvoltage

Do not appIy voltaqes exceeding the maximum

specified rated voltages. Voltage up to the surge
voltage rating are acceptable for short periods of
time. Ensure that the sum of the DC voltage and
the superimposed AC ripple voltage does not
exceed the rated voltage.

(4) Ripple Current

Do not apply ripple currents exceeding the maximum

specified value. For high ripple current applications,
use a capacitor designed for high rippIe currents
or contact us with your requirements.
Ensure that allowable ripple currents superimposed
on low DC bias voltages do not cause reverse voltage
conditions.

1.4 Using Two or More Capacitors in Series
or Parallel

(1) Capacitors Connected in Parallel

The circuit resistance can closely approximate the

series resistance of the capacitor causing an
imbalance of ripple current loads w ithin the
capacitors. Careful design of wiring methods can
minimize the possibility of excessive ripple currents
applied to a capacitor.

(2) Capacitors Connected in Series

Nor mal DC leakage current differences among

capacitors can cause voltage imbalances. The use
of voltage divider shunt resistors with consideration
to leakage currents, can prevent capacitor voltage
imbaIances.

1.5 Capacitor Mounting Considerations

(1) DoubIe - Sided Circuit Boards

Avoid wiring Pattern runs which pass between

the mounted capacitor and the circuit board. When
dipping into a solder bath, excess solder may collect
under the capacitor by capillar y action and

shortcircuit the anode and cathode ter minals.

(2) Circuit Board Hole Positioning

The vinyl sleeve of the capacitor can be damaged

if solder passes through a lead hole for
subsequently processed parts. Special care when
locating hole positions in pr oximity to capacitors is
recommended.

(3) Circuit Board Hole Spacing

The circuit board holes spacing should match the

capacitor lead wire spacing within the specified
tolerances. Incorrect spacing can cause excessive
lead wire stress du ring the insertion process. This
may resuIt in p remature capacitor failure due to
short or open circuit, increased leakage current,
or electrolyte leakage.

(4)Land/Pad Pattern

The circuit board land/pad pattern size for chip

capacitors is specified in the following table.

[Table of Board Land Size vs. Capacitor Size]

B(φ4)
C(φ5)
D(φ6.3)
E(φ8 x 6.2L)
F(φ8 x 10.2L)
G(φ10 x 10.2L)

Among others, when the size a is wide , back fillet can
not be made, decreasing fitting strength.

❉ Decide considering mounting condition, solderability
and fitting strength, etc. based on the design
standards of your company.

(5)Clearance for Case Mounted Pressure
Relief Vents

Capacitors with case mounted pressure relief vents
require sufficient clearance to allow for proper vent
operation. The minimum c learances are dependent
on capacitor diameters as follows.

f6.3 to f16 mm : 2 mm minimum,
f18 to f35 mm : 3 mm minimum.

f40 mm or greater: 5 mm minimum

(6)Clearance for Seal Mounted Pressure
Relief Vents

A hole in the circuit board directly under the seal

vent location is required to allow proper release

of pressure.

(7)Wiring Near the Pressure Relief Vent

Avoid locating high voltage or high current wiring

or circuit board paths above the pressure relief

vent. Flammable, high temperature gas exceeding

100°C may be rel eased which could dissolve the

wire insulation and ignite.

(8)Circuit Board Patterns Under the Capacitor

Avoid circuit board runs under the capacitor as

electrolyte leakage could cause an electrical short.

(9)Screw Terminal Capacitor Mounting

● Do not orient the capacitor with the screw terminal

side of the capacitor facing downwards.

● Tighten the terminal and mounting bracket screws

within the torque range specified in the

specification.

1.6Electrical Isolation of the Capacitor

Completely isolate the capacitor as follows.

● Between the cathode and the case (except for
axially leaded B types) and between the anode

terminal and other circuit paths.

● Between the extra mounting terminals (on T types)

and the anode terminal, cathode terminal, and

other circuit paths.

1.7Capacitor Sleeve

The vinyl sleeve or laminate coating is intended for
mar king and identification purposes and is not meant
to electrically insulate the capacitor.
The sleeving may split or crack if immersed into
solvents such as toluene or xylene, and then exposed
to high temperatures.

2. Capacitor Handling Techniques

2.1Considerations Before Using

(1) Capacitors have a finite life. Do not reuse or
recycle capacitors from used equipment.
(2) Transient recovery voltage may be generated in

the capacitor due to dielectric absorption. If
required, this voltage can be discharged with a
resistor with a value of about 1 kΩ.

(3) Capacitors stored for long periods of time may

exhibit an increase in leakage current. This can
be corrected by gradually applying rated voltage
in series with a resistor of approximately 1 kΩ.

(4) If capacitors are dropped, they can be damaged

mechanically or electrically. Avoid using dropped
capacitors.

(5) Dented or crushed capacitors should not be

used. The seal integrity can be compromised
and loss of electrolyte/shortened life can result.

2.2Capacitor Insertion

(1) Verify the correct capacitance and rated voltage

of the capacitor.

(2) Verify the correct polarity of the capacitor before

inserting.

(3)

Verify the correct hole spacing before insertion
(land pattern size on chip type) to avoid stress
on the terminals.

(4) Ensure that the auto insertion equipment lead

clinching operation does not stress the capacitor
leads where they enter the seal of the capacitor.
For chip type capacitors, excessive mounting
pressure can cause high leakage current, short
circuit, or disconnection.

2.3Manual Soldering

(1) Observe temperature and time soldering

specifications or do not exceed temperatures of
350°C for 3 seconds or less.

(2) If lead wires must be formed to meet terminal

board hole spacing, avoid stress on the leadwire
where it enters the capacitor seal.

(3) If a soldered capacitor must be removed and

reinserted, avoid excessive stress to the capacitor
leads.

(4) Aviod touching the tip of the soldering iron to the

capacitor, to prevent melting of the vinyl sleeve.

Always consider safety when designing equipment
and circuits. Plan for worst case failure modes such
as short circuits and open circuits which could occur
during use.

(1)Provide protection circuits and protection devices

to allow safe failure modes.

(2)Design redundant or secondary circuits where

possible to assure continued operation in case of
main circuit failure.

Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use.
Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail.

2.4 Flow Soldering

(1) Don not immerse the capacitor body into the

solder bath as excessive internal pressure could

result.
(2) Observe proper soldering conditions (temperature,

time, etc.). Do not exceed the specified limits.
(3) Do not allow other parts or components to touch

the capacitor during soldering.

2.5 Reflow Soldering for Chip Capacitors

(1) For reflow, use a thermal conduction system such

as infrared radiation (IR) or hot blast. Vapor heat

transfer systems (VPS) are not recommended.
(2) Observe proper soldering conditions (temperature,

time, etc.). Do not exceed the specified limits.
(3) Reflow should be performed one time. Consult us

for additional reflow restrictions.

2.6 Other Soldering Considerations

Rapid temperature rises during the preheat
operation and resin bonding operation can cause
cracking of the capacitor vinyl sleeve. For heat
curing, do not exceed 150°C for a maximum time of
2 minutes.

2.7 Capacitor Handling after Soldering

(1) Avoid movement of the capacitor after soldering

to prevent excessive stress on the leadwires
where they enter the seal.

(2) Do not use the capacitor as a handle when

moving the circuit board assembly.

(3) Avoid striking the capacitor after assembly to

prevent failure due to excessive shock.

2.8 Circuit Board Cleaning

(1) Circuit boards can be immersed or ultrasonically

cleaned using suitable cleaning solvents for up
to 5 minutes and up to 60°C maximum
temperatures. The boards should be thoroughly
rinsed and dried.
Recommended cleaning solvents include
Pine Alpha ST-100S, Sunelec B-12, DK Beclear
CW-5790, Aqua Cleaner 210SEP, Cold Cleaner
P3-375, Telpen Cleaner EC-7R, Clean-thru 750H,

(2) Avoid using the following solvent groups unless

specifically allowed for in the specification;

● Halogenated cleaning solvents: except for solvent
resi stant capacitor types, halogenated solvents
can permeate the seal and cause internal
capacitor corrosion and failure. For solvent
resistant capacitors, carefully follow the
temperature and time requirements of the
specificaion. 1-1-1 trichloroe thane should never
be used on any aluminium electrolytic capacitor.

● Alkali solvents: could attack and dissolve the
aluminum case.

● Petroleum based solvents: deterioration of the
rubber seal could result.

● Xylene: deterioration of the rubber seal could
result.

● Acetone: removal of the ink markings on the
vinyl sleeve could result.

(3) A thorough drying after cleaning is required to

remove residual cleaning solvents which may be
trapped between the capacitor and the circuit
board. Avoid drying temperatures which exceed
the maximum rated temperature of the capacitor.

(4) Monitor the contamination levels of the cleaning

solvents during use by electrical conductivity, pH,
specific gravity, or water content. Chlorine levels
can rise with contamination and adversely affect
the performance of the capacitor.

2.9Mounting Adhesives and Coating Agents

When using mounting adhesives or coating agents to
control humidity, avoid using materials containing
halogenated solvents. Also, avoid the use of
chloroprene based polymers.

✽ After applying adhesives or coatings, dry thoroughly

to prevent residual solvents from being trapped
between the capacitor and the circuit board.

3. Precautions for using capacitors

3.1Environmental Conditions

Capacitors should not be used in the following
environments.
(1) Temperature exposure above the maximum rated

or below the minimum rated temperature of the

capacitor.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could

condense on the capacitor.
(4) Exposure to toxic gases such as hydrogen sulfide,

sulfuric acid, nitric acid, chlorine, or ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding

specified requirements.

3.2Electrical Precautions

(1) Avoid touching the terminals of the capacitor as

possible electric shock could result. The exposed
aluminium case is not insulated and could also
cause electric shock if touched.

(2)Avoid short circuiting the area between the

capacitor terminals with conductive materials
including liquids such as acids or alkaline solutions.

4. Emergency Procedures

(1) If the pressure relief vent of the capacitor

operates, immediately turn off the equipment and
disconnect from the power source. This will
minimize additional damage caused by the
vaporizing electrolyte.

(2) Avoid contact with the escaping electrolyte gas

which can exceed 100°C temperatures.
If electrolyte or gas enters the eye, immediately
flush the eye with large amounts of water.
If electrolyte or gas is ingested by mouth, gargle
with water. If electrolyte contacts the skin, wash
with soap and water.

5. Long Term Storage

Leakage current of a capacitor increases with long
storage times. The aluminium oxide film deteriorates
as a function of temperature and time. If used
without reconditioning, an abnormally high current
will be required to restore the oxide film. This current
surge could cause the circuit or the capacitor to fail.
Capacitor should be reconditioned by applying rated
voltage in series with a 1000 Ω, current limiting
resistor for a time period of 30 minutes.

5.1Environmental Conditions (Storage)

Capacitors should not be stored in the following
environments.
(1) Temperature exposure above 35°C or below 15 °C.
(2) Direct contact with water, salt water, or oil.
(3) High humidity conditions where water could

condense on the capacitor.

(4) Exposure to toxic gases such as hydrogen

sulfide,sulfuric acid, nitric acid, chlorine, or

ammonia.
(5) Exposure to ozone, radiation, or ultraviolet rays.
(6) Vibration and shock conditions exceeding

specified requirements.

Design, Specifications are subject to change without notice. Ask factory for technical specifications before purchase and/or use.
Whenever a doubt about safety arises from this product, please inform us immediately for technical consulation without fail.

6. Capacitor Disposal

Mar. 2005

When disposing of capacitors, use one of the
following methods.

● Incinerate after crushing the capacitor or

puncturing the can wall (to prevent explosion due
to internal pressure rise). Capacitors should be

incinerated at high temperatures to prevent the
release of toxic gases such as chlorine from the
polyvinyl chloride sleeve, etc.

● Dispose of as solid waste.

● Local laws may have specific disposal

requirements which must be followed.

The application guidelines above are taken from:

Technical Report EIAJ RCR-2367 issued by the Japan
Electronic Industry Association, Inc. ­Guideline of notabilia for aluminium electrolytic
capacitors with non-solid electrolytic for use in
electronic equipment.

Refer to this Technical Report for additional details.
